If you're not too wild about the idea of paying for a whole new set of sunglasses with your prescription built in (they can be fairly pricy!), you may want to slip on a pair of sunglasses that fit over your everyday prescription eyeglasses.
If you don't drive much, but you need a pair of prescription sunglasses for long walks and outdoor activities, you may find photochromics to be a less expensive option than a pair of regular eyeglasses and a pair of prescription sunglasses.
You can choose more than one service, so if you need the Vision Center as well as a Tire & Lube department, for example, you can select them both and have your oil changed while you get your eyes examined and choose your eyeglasses.
If you're in need of an eye exam and would prefer to get your exam and eyewear in the same place, or you'd just prefer to shop for eyeglasses in person, you can visit the store's website and enter your zip code in the store locator box.
Not all styles will be this much as it depends on where you shop and the brands and materials you choose, but be prepared to pay more for your rimless eyeglasses than you would for an average metal or plastic frame with plastic lenses.
